Introduction

FORM QTC3-EG6 (1118)

Quantech™ is proud to present the Model QTC3 Air-Cooled Scroll Chiller.

FEATURES AND BENEFITS

Installation

The QTC3 chiller arrives as a factory-assembled package ready to be installed outdoors, either on the roof or at ground level. The air-cooled condensers eliminate the capital, installation and maintenance costs of a cooling-tower circuit.

The QTC3 weighs less and has s smaller footprint than other chillers in its class. In fact, it is 20-35% lighter weight than the market average chiller. When the chiller is roof-mounted in new construction, the cost of the support structure can be reduced. In building retrofits, the QTC3 can provide the largest capacity in a given space and existing structure.

Power hook-up could not be any easier with the standard single-point connection. A terminal block, disconnect switch or circuit breaker is provided to meet the unique needs of every project and minimize installation time and labor. The factory-installed control transformer steps down the power voltage to the control voltage.

Chilled-water piping is also simple. The water connections are factory-piped to the outside of the unit, for ease of access. Factory-cut grooves, or optional flanges, make piping connections simple. Optional factory-installed pump kits eliminate the time, cost, and mechanical-equipment room space necessary to install chilled-water pumps.

Press the start button with confidence – your QTC3 has been run-tested at the factory to ensure that you will have a successful start-up.

Reliability

The QTC3 chiller is proven and reliable, designed to reduce service calls. The scroll compressors have logged hundreds of thousands of operating hours in numerous different applications. The corrosive-resistant condenser heat exchangers have been specifically designed for stationary HVAC applications and have undergone extensive laboratory and field testing to extend chiller life and improve performance. They are also more rigid than standard condenser coils, making them less susceptible to damage during rigging, lifting, and installation of the chiller.

Components are designed to keep the chiller up-and-running. A factory-installed water strainer prevents debris from affecting unit flow and/or heat transfer. The rugged thermaldispersion flow switch is factory-installed at the optimum location in the piping for superior flow sensing, reducing the potential for nuisance trips. Intelligent controls protect the chiller while keeping it online, for maximum uptime. Exterior panels of the chiller are powder-coated with highly durable corrosion-resistant paint.

Introduction (Cont'd)

Efficiency

QTC3 high-efficiency chillers, with their innovative control algorithms, offer industry-leading energy efficiency. Real-world energy efficiency is measured by IPLV (off-design) performance, and QTC3 chillers provide some of the best IPLVs in their class.

QTC3 also offers an efficiency choice. In addition to the high-efficiency units, QTC3 chillers are available in standard efficiency models with smaller footprints and lower capital costs.

Only pay for the chiller you need – the multi-efficiency levels of the QTC3 allow you to decide the best investment for the job.

Flexibility

The QTC3 chiller offers a number of options designed to operate reliably across a wide range of customer needs. It can cool glycol down to 10°F (-12°C). It can provide heat recovery up to 140°F (60°C), with up to 85% of total heat rejection captured.

When factory-mounted pump kits are considered, there are now more pump sizes to choose from. The optional kits come standard with valves, pressure ports, flow switch, and strainer for quick hook-up, and frost protection to prevent freeze-up. There are also more pump options available: variable-speed drives, dual pumps, service shut-off valves, expansion tanks, and additional test ports for temperature and pressure sensing.

Standard low sound and multiple sound attenuation options allow flexibility in locating the chiller, and reduce the cost for field-constructed barriers.

Sustainability

The QTC3 makes you a leader in sustainability through innovation, not added cost. With the combination of R-410A refrigerant, which has no ozone-depletion potential, and stateof-the-art heat exchanger technology that allows refrigerant charge to be reduced by as much as 30%, the QTC3 chiller provides the most ecologically friendly equipment. Partnered with its low-sound properties for noise pollution prevention, this chiller is a true earth-friendly offering.

Introduction (Cont'd)

Communications

The QTC3 chiller comes standard with native communication capability for BACnet (MS/ TP), Modbus, and N2, with optional capabilities available for LON. The standard unit capabilities include built-in-scheduling, remote start-stop, remote water temperature reset and up to two steps of demand (load) limiting depending on model. The standard control panel can be directly connected to a building automated system via the standard factoryinstalled RS232 communication port.

Serviceability

Minimal maintenance is required to keep the unit operating at maximum performance. If service should ever be required, the QTC3 chiller has been designed to simplify the work, keeping costs down. The layout of the chiller locates all the major components that can be serviced near the outside edge. The condenser heat exchangers are light enough that no crane is required for replacement. And when it’s time to clean them, city tap water, with water pressure typical of a spray from a common garden hose, is all that’s needed.

Equipment Overview

The 55 - 230 Ton (195 - 800 kW) QTC3 models are shipped complete from the factory ready for installa tion and use. The unit is pressure-tested, evacuated, and fully charged with a zero Ozone Depletion Potential Refrigerant R-410A and includes an initial oil charge. After assembly, a complete operational test is performed with water flowing through the evaporator to as sure that the refrigeration circuit operates correctly.

The unit structure is heavy-gauge, galvanized steel. This galvanized steel is coated with baked-on powder paint, which, when subjected to ASTM B117 1000 hour, salt spray testing, yields a minimum ASTM 1654 rating of “6”. Units are designed in accordance with NFPA 70 (National Electric Code), ASHRAE/ANSI 15 Safety code for mechanical refrigeration, ASME and rated in accordance with AHRI Standard 550/590.

COMPRESSORS

The chiller has suction-gas cooled, hermetic scroll com pressors. The QTC3 compressors incorporate a compli ant scroll design in both the axial and radial direction. All rotating parts are statically and dynamically balanced. A large internal volume and oil reservoir provides greater liquid tolerance. Compressor-crankcase heaters are also included for extra protection against liquid migration. Power wiring is routed through liquid tight conduit.

BRAZED PLATE EVAPORATOR

The compact, high efficiency Brazed Plate Heat Exchanger (BPHE) is constructed with 316L stainless steel corrugated channel plates with a filler material between each plate. It offers excellent heat transfer performance with a compact size and low weight, reducing structural steel requirements on the job site.

LD18425

QUANTECH

Equipment Overview (Cont'd)

The heat exchanger is manufactured in a precisely controlled vacuum-brazing process that allows the filler material to form a brazed joint at every contact point between the plates, creating complex channels. The arrangement is similar to older plate and frame technology, but without gaskets and frame parts.

FORM QTC3-EG6 (1118)

LD18426

Water inlet and outlet connections are grooved for compatibility with field supplied ANSI/ AWWA C-606 couplings.

A 20 mesh wye-strainer is provided as standard to provide protection at the evaporator inlet, particularly at system start-up when construction debris may be present in the piping system.

The evaporator is equipped with a thermostat-controlled heater. The heater provides freeze protection for the evaporator down to -20°F (-29°C) ambient. The evaporator is covered with 3/4” flexible, closed-cell, foam insulation (K=0.25).

A factory-wired flow switch is standard, installed in a pipe section at the outlet of the evaporator.

FORM QTC3-EG6 (1118)

Equipment Overview (Cont'd)

Unit alarm contacts are standard. Contacts for remote chilled liquid temperature reset and two steps of demand load limiting are also standard, for projects without BAS or for redundancy.

Maximum reliability is achieved through intelligent control. Run hours and starts are averaged across all compressors automatically, and between both pumps of the optional dual pump hydro-kit. When compressors are cycled off, an anti-recycle timer ensures the motors have time to cool before starting again, for the maximum service life. At unit shutdown, the unit pumps down automatically to prevent liquid refrigerant from entering the compressors at restart, which can cause premature bearing wear and other compressor damage.

Liquid temperature sensors provide feedback to the controller, and logic predicts when additional capacity will be required based on how quickly the unit has loaded or unloaded in the past. This prevents unnecessary compressor cycling and helps maintain setpoint accurately.

If there is a problem that prevents the unit operating properly, the controls are designed to allow the unit to operate safely while making as much capacity as possible. For example, if airflow to the condenser coil is diminished due to a dirty coil, the chiller will unload slightly to provide maximum capacity possible while remaining within the unit operating envelope.

If a fault prevents the unit from starting or causes it to shutdown, the chiller will attempt to restart three times. If it cannot start, a manual reset is required to alert the operator about the fault condition. The fault history is stored in the unit controller RTC memory for the last six fault shutdown conditions. An RS-232 port provides capability to print hard copy reports (printer available separately).

All controls are contained in a NEMA 3R cabinet with a hinged outer door and includes a liquid crystal display (LCD) with light emitting diode (LED) backlighting for outdoor viewing. There are two display lines, each with twenty text characters per line, and a color coded 12-button non-tactile keypad with sections for display, entry and printing.

NOTE: Placement on a level surface of free of obstructions (including snow, for winter operation) or air circulation ensures rated performance, reli-

able operation, and ease of maintenance. Site restrictions may compromise minimum clearances indicated below, resulting in unpredictable

airow patterns and possible diminished performance. The unit controls will optimize operation without nuisance high-pressure safety cut-

outs; however, the system designer must consider potential performance degradation. Access to the unit control center assumes the unit is no higher than on spring isolators. Recommended minimum clearances: Side to wall – 6'; rear to wall – 6'; control panel to end wall – 4'0''; top – no obstructions allowed; distance between adjacent units – 10'. No more than one adjacent wall may be higher than the unit.

NOTE:

Placement on a level surface of free of obstructions (including snow, for winter operation) or air circulation ensures rated performance, reli-

able operation, and ease of maintenance. Site restrictions may compromise minimum clearances indicated below, resulting in unpredictable

airow patterns and possible diminished performance. The unit controls will optimize operation without nuisance high-pressure safety cut-outs;

however, the system designer must consider potential performance degradation. Access to the unit control center assumes the unit is no higher than on spring isolators. Recommended minimum clearances: Side to wall – 6'; rear to wall – 6'; control panel to end wall – 4'0''; top – no obstructions allowed; distance between adjacent units – 10'. No more than one adjacent wall may be higher than the unit.

largest motor plus 100% of the rated load amps for all other loads included in the circuit, per N.E.C. Article 430-24. If the optional Factory Mounted Control Transformer is provided, add the following MCA values to the electrical tables for the system providing power to the transformer: -17, add 2.5 amps; -28, add 2.3 amps; -40, add

1.5 amps, -46, add 1.3 amps; -58, add 1 amps.

amps for all loads included in the circuit, per N.E.C. Article 440.

plus 100% of the rated load amps for all other loads included in the circuit to avoid nuisance trips at start-up due to lock rotor amps. It is not recommended in applications where brown outs, frequent starting and stopping of the unit, and/or operation at ambient temperatures in excess of 95ºF (35ºC) is anticipated.

4. Maximum fuse size is based upon 225% of the rated load amps for the largest motor plus 100% of the rated load amps for all other loads included in the circuit, per N.E.C. Article 440-22.

5. Circuit breakers must be UL listed and CSA certied and maximum size is based on 225% of the rated load amps for the largest motor plus 100% of the rated load amps for all other loads included in the circuit. Otherwise, HACR-type circuit breakers must be used. Maximum HACR circuit breaker rating is based on 225% of the rated load amps for the largest motor plus 100% of the rated load amps for all other loads included in the circuit.

6. The “INCOMING WIRE RANGE” is the minimum and maximum wire size that can be accommodated by the unit wiring lugs. The (2) preceding the wire range indicates the number of termination points available per phase of the wire range speci-

ed. Actual wire size and number of wires per phase must be determined based on

the National Electrical Code, using copper connectors only. Field wiring must also comply with local codes.

7. A ground lug is provided for each compressor system to accommodate a eld grounding conductor per N.E.C. Table 250-95. A control circuit grounding lug is also supplied.

8. The supplied disconnect is a “Disconnecting Means” as dened in the N.E.C. 100, and is intended for isolating the unit for the available power supply to perform maintenance and troubleshooting. This disconnect is not intended to be a Load Break Device.

9. Field Wiring by others which complies to the National Electrical Code & Local Codes.

Application Data

UNIT LOCATION

The QTC3 chillers are designed for outdoor installation. When selecting a site for installation, be guided by the following conditions:

A. For outdoor locations of the unit, select a place having an adequate supply of fresh air

for the condenser.

B. Avoid locations beneath windows or between structures where normal operating

sounds may be objectionable.

C. Installation sites may be either on a roof, or at ground level. (See FOUNDATION.)

D. The condenser fans are the propeller-type, and are not recommended for use with duct

work in the condenser air stream.

E. When it is desirable to surround the unit(s), it is recommended that the screening be

able to pass the required chiller CFM without exceeding 0.1" of water external static pressure.

FORM QTC3-EG6 (1118)

F. Protection against corrosive environments is available by supplying the units with ep-

oxy coating on the condenser coils. The epoxy coils should be offered with any units being installed at the seashore or where salt spray may hit the unit.

In installations where winter operation is intended and snow accumulations are expected, additional height must be provided to ensure normal condenser air flow.

Recommended clearances for units are given in the Unit Dimensions on page 26. When the available space is less, the unit(s) must be equipped with the discharge pressure transducer option to permit high pressure unloading in the event that air recirculation were to occur.

FOUNDATION

The unit should be mounted on a flat and level foundation, ground or roof, capable of supporting the entire operating weight of the equipment. Operating weights are given in the Physical Data and Nominal Ratings on page 22.

Roof Locations – Choose a spot with adequate structural strength to safely support the entire weight of the unit and service personnel. Care must be taken not to damage the roof during installation. If the roof is “bonded”, consult the building contractor or architect for special installation requirements. Roof installations should incorporate the use of springtype isolators to minimize the transmission of vibration into the building structure.

Ground Level Installations – It is important that the units be installed on a substantial base that will not settle, causing strain on the liquid lines and resulting in possible leaks. A one-piece concrete slab with footers extending below the frost line is highly recommended. Additionally, the slab should not be tied to the main building foundation as noises will telegraph.

QUANTECH

FORM QTC3-EG6 (1118)

Application Data (Cont'd)

Mounting holes (5/8" diameter) are provided in the steel channel for bolting the unit to its foundation. See Unit Dimensions on page 26.

For ground level installations, precautions should be taken to protect the unit from tampering by or injury to unauthorized persons. Screws on access panels will prevent casual tampering; however, further safety precautions, such as unit enclosure options, a fencedin enclosure, or locking devices on the panels may be advisable. Check local authorities for safety regulations.

VARIABLE PRIMARY FLOW

Quantech recommends a maximum 10% per minute flow rate of change, based on design flow, for variable primary flow applications. Eight to 10 gallons per chiller ton (8.6 to 10.8 liter per cooling kW) is recommended for the system liquid volume. Insufficient system volume and rapid flow changes can cause control problems or can even cause chiller shutdowns. There are many other design issues to evaluate with variable primary flow systems. Consult your Quantech Sales Office for more information about successfully applying QTC3 chillers.

CHILLED LIQUID PIPING

The chilled liquid piping system should be laid out so that the circulating pump discharges into the evaporator. The inlet and outlet evaporator liquid connections are given in DIMENSIONS.

Hand stop valves are recommended for use in all lines to facilitate servicing. Drain connections should be provided at all low points to permit complete drainage of the evaporator and system piping. Additionally, a strainer (20 mesh) is recommended for use on the INLET line to the evaporator.

Pressure gauge connections are recommended for installation in the inlet and outlet water lines. Gauges are not furnished with the unit and are to be furnished by other suppliers.

The chilled liquid lines that are exposed to outdoor ambients should be wrapped with a supplemental heater cable and covered with insulation. As an alternative, ethylene glycol should be added to protect against freeze-up during low ambient periods.

A flow switch is available as an accessory on all units. The flow switch (or its equivalent) must be installed in the leaving water piping of the evaporator and must not be used to start and stop the unit.
